The network, measured.

This is the part nobody writes down, and the part that costs an afternoon to discover. The public endpoint serves ordinary reads without complaint: balances, contract calls, blocks, receipts.

Two things it refuses. It does not keep archive state, so asking for a balance at a block from months ago returns an error rather than a number. And eth_getLogs is capped by the size of the response rather than by the block range — a hundred blocks of a busy contract can exceed it while ten thousand blocks of a quiet one do not.

The practical consequence is that reading a contract's history means walking it in windows and shrinking the window when a request comes back refused, rather than picking a range and hoping.

Blocks arrive roughly every 0.104 seconds — about 833,173 a day, close to seventy times Ethereum's rate. Recent blocks carried an average of 6.0 transactions each.

The consequence that matters is not the speed itself. It is the ordering: Robinhood Chain sequences transactions by arrival rather than by fee. Paying more gas buys no position at all, which makes every priority-fee strategy from other chains pointless here.

What it rewards instead is latency — preparing everything in advance so a transaction can leave the instant it becomes valid. Why that changes the approach.
